The work of preparing International Standards is normally carried out through ISO t
14、echnical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates clos
15、ely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draf
16、t International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this docum
17、ent may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 15031-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. This first edition of ISO 15031-2 cancels and re
18、places ISO/TR 15031-2:2004, which has been technically revised. ISO 15031 consists of the following parts, under the general title Road vehicles Communication between vehicle and external equipment for emissions-related diagnostics: Part 1: General information and use case definition Part 2: Guidanc

20、2010ISO 15031-2:2010(E) ISO 2010 All rights reserved vIntroduction 0.1 Overview The various parts of ISO 15031, when taken together, provide a coherent, consistent set of specifications for facilitating emissions-related diagnostics. ISO 15031-2 to ISO 15031-7 are based on recommended practices of t
21、he Society of Automotive Engineers (SAE). This part of ISO 15031 is based on SAE J1930. See ISO 15031-1 for general information and an introduction to ISO 15031. As the number of sophisticated electrical and electronic (E/E) systems on motor vehicles has increased, the number of terms, abbreviations
22、 and acronyms which describe various components of these systems has increased enormously. The nomenclature used to convey automotive service information is being standardized in order to more accurately convey information to technicians faced with the diagnosis and repair of increasingly complex ve
23、hicles. To be properly descriptive, each type of automotive nomenclature requires a consistent methodology. This document is concerned with a methodology for naming objects and systems and with the set of words from which names are built. The procedure allows the complete description of objects and
24、systems without ambiguity and the generation of names which distinguish among similar objects or systems without confusion but with brevity. Using terms which are well defined within the context of the automotive service industry, the procedure allows already existing, imprecise, names to be suitabl
25、y changed and future names to be assigned in a predictable way that will reliably convey meaning to the technician. 0.2 SAE document reference concept This part of ISO 15031 references several SAE documents which contain all the terms, data and diagnostic trouble code (DTC) definitions. This is illu
26、strated in Figure 1. Additional information on the content of the referenced documents is given below. SAE J1930: the document is concerned with a procedure for naming objects and systems and with the set of words from which names are built. It references SAE J1930-DA, which contains all standardize
27、d naming objects, terms and abbreviations. SAE J1979: the document is concerned with the definition of emissions-related diagnostic services (diagnostic test modes). It references SAE J1979-DA, which contains all standardized data items like PIDs, Test Ids, Monitor Ids and InfoType Ids. SAE J2012: t
28、he document is concerned with the procedure for defining emissions-related diagnostic trouble codes. It references SAE J2012-DA, which contains all standardized data items like DTCs and failure type bytes (FTBs). BS ISO 15031-2:2010ISO 15031-2:2010(E) vi ISO 2010 All rights reservedKey 1 SAE Digital
29、 Annexes Figure 1 SAE Digital Annex document reference 0.3 SAE J1930-DA Digital Annex This part of ISO 15031 references the SAE J1930-DA. The SAE J1930-DA is concerned with the terms, abbreviations and acronyms which are defined according to the procedure for naming objects and systems. The SAE J193
30、0-DA includes several appendices: Approved terms; SAE J1979 parameter ID (PID) acronyms; Glossary and Control Module Naming; Figures to assist in the identification of the proper terms; Historical reference for acronym usage in previous publications. 0.4 SAE Digital Annex revision procedure New emis
31、sions-related regulatory requirements drive new in-vehicle technology to lower emissions. New technology-related OBD (on-board diagnostic) monitor data and diagnostic trouble codes need to be standardized to support the external (off-board) “generic” test equipment. All relevant information is propo
32、sed by the automotive industry represented by members of the appropriate SAE task force.

36、usage of terms, definitions, abbreviations and acronyms used in emissions-related diagnostics, with respect to the communication between road vehicles and external equipment used in that field. It also specifies a procedure for constructing new terms. As it gives recommended usage of diagnostic term
37、s applicable to electrical/electronic systems, it also makes reference to related mechanical terms, definitions, abbreviations and acronyms. This part of ISO 15031 is applicable to all light-duty gasoline and diesel passenger vehicles and trucks, and to heavy-duty gasoline vehicles. Specific applica
38、tions of this document include diagnostic, service and repair manuals, bulletins and updates, training manuals, repair databases, underhood emission labels and emission certification applications. The introduction of a term, abbreviation or acronym not covered by this part of ISO 15031 is not prohib
39、ited. This part of ISO 15031 is intended to help industry provide standard terms, definitions, abbreviations and acronyms with a view to establishing a common terminology for diagnostic tools and publications. This part of ISO 15031 references the SAE J1930-Digital Annex (DA), which includes all sta
40、ndard terms, definitions, abbreviations and acronyms. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (includi

The SAE J1930 committee may approve
44、these terms that are already considered industry standard. These terms fall into three categories: a) acronyms that do not logically fit the term; b) acronyms existing at the component level, i.e. their terms contain the base word or noun that describes the generic item that is being further defined
45、; c) acronyms for terms that appear to contain the base word, but are frequently used as a modifier to another base word. This use may possibly be thought of as following the methodology since the acronym is normally used as a modifier. 5 Document overview Figure 2 illustrates the document reference

Appropriate modifiers are added to
49、a base word until an object or system is uniquely specified within its context. When building names, select the most descriptive base word from the Glossary of Terms (see SAE J1930-DA). Add modifiers as necessary or as desirable within the context, in the order of most significance to least significance. The most significant word will be the base word, which denotes the basic function of the object. The most significant modifier will be adjacent to the base word, the second
